Two terpene synthases in resistant Pinus massoniana contribute to defense against Bursaphelenchus xylophilus.

Plant, Cell and Environment, 2020
Pine wood nematode (PWN; Bursaphelenchus xylophilus), a destructive pest of Pinus massoniana, is causing a severe epidemic of pine wilt disease in China. When invaded by PWN, resistant P.

Terpene und Carotinoide

1982
Terpene kommen vor allem in Harzen und atherischen Olen vor. Sie werden in der Riechstoffindustrie zur Herstellung von Parfumen und zur Parfumierung von Waschmitteln und Kosmetika verwendet.

Chromatostrip isomerization of terpenes

Journal of Chromatography A, 1965
Abstract Isomerization of the monoterpene hydrocarbons of black pepper oil occurred during isolation by thin-layer chromatography. α-Thujene, α-pinene, β-pinene, myrcene, 3-carene, limonene, β-phellandrene, ψ-terpinene, terpinolene and p -cymene were each eluted from chromatostrips and were all found to chromatograph without change.

Autoxidation of terpenic aldehydes—I

Tetrahedron, 1973
Abstract The influence of steric factors on the autoxidation of aldehydes having tertiary formyl groups has been investigated. These afford nor-derivatives by loss of carbon monoxide, and carboxylic acids. Steric interactions have been shown to affect strongly the ratio between carboxylic acid and nor-derivatives and, in addition, to increase the ...

Nature-driven approaches to non-natural terpene analogues.

Natural product reports (Print), 2020
Covering: up to 2019The reactions catalysed by terpene synthases belong to the most complex and fascinating cascade-type transformations in Nature. Although many accept only one natural terpene precursor and convert it with high selectivity into only one

Terpene Resins

2005
Publisher Summary Terpenes are widely spread in nature, mainly in plants as constituents of essential oils. Some terpenes are pure hydrocarbons, but there are also terpenes with hydroxyl functions and carbonyl functions. Terpenes provide plants and flowers fragrance.

Campher und Terpene [PDF]

open access: possible, 1912
Carvon erweist sich im Tierversuche als nicht sehr aktiv, es zeigt hauptsachlich paralysierende Wirkungen im Gegensatze zu seinen Isomeren: zum Campher und Fenchon. Von diesen unterscheidet sich Carvon auch chemisch: so erleidet es bekanntlich leicht eine Hydrolyse unter Bildung von Oxytetrahydrocarvon und es ist leicht anzunehmen, das Carvon eine ...

Terpenes and steroids

1981
The polyketides form a group of metabolites which are based on patterns of repeating acetate units (Chapter 3). There is another group of metabolites, widespread in nature and rich in diverse chemistry, which is based on another repeating unit: isoprene (4.1).

Bacterial terpene cyclases.

Natural product reports (Print), 2016
Covering: up to 2015. This review summarises the accumulated knowledge about characterised bacterial terpene cyclases. The structures of identified products and of crystallised enzymes are included, and the obtained insights into enzyme mechanisms are ...

Terpenes and Terpenoids

2018
Terpenes and their derivatives, the terpenoids, are synthetized from a five carbon atom isoprene unit. These units are added to each other to give rise to compounds of different complexities. The synthesis takes place either in the cytosol (MVA pathway) or within the plastids (MEP pathway).
